ASH EJEoroR.

T 0 all whom it may concern:

Be it known that I, EUGENE HAHN, a citizen of Hungary (having declared'my intentions of becoming a citizen of the United States), residing in Philadelphia, Pennsylvania, have invented certain Improvements in Ash Ejectors, of which the following is a specification.

My invention relates toash ejectors, and the object of my invention is the pro-vision of certain improvements in conveyors of the type forming the subject of my co-pending application, Serial No. 382,9t9, in which I have described an ash ejector of the suction type adapted to use on vessels and the like, and having a. closure cap provided for the outer extremity of the ejector pipe, said cap being so interconnected with the valve controlling the flow of steam, compressed air or' other fluid into theejector duct that the opening and closing of the one involves the opening and closing of the other.

My present invention comprises mechanism whereby the simple movement of a single actuating member either throws the ej ector into operation or completely shuts it off, said single actuating member not only con trolling the flow of fluid through the duct but the various closures as well, as will hereinafter be more fully described.

In the accompanying drawings:

Figure 1, is a side elevation of my improved ejector;

Fig. 2, is a plan view of the ejector;

Fig. 3, is a vertical section of the ejecto duct showing the outer closure;

Figs. 4 and 5, are, respectively, aside elevation and plan view showing the details of the connection between operating rods and water valve, and

7 Figs. 6 and 7, are, respectively, a side ele vation and plan view of a modification of my device.

l/Vith reference to the drawings, the ejector consists of an inclined duct1, having at the lower end thereofa substantially horizontal'po-rtion 2, having therein an ash inlet opening 3 and an air inlet 4-. A noz- Specification of Letters Patent.

the present instance extends upwardlyat one side of the ejector, and has located in the said vertical portion a valve 7, which controls the flow of the fluid through the pipe. Anoperating spindle 8- of the valve" '7 extends from the said valve laterally, and

the arms 9 and 10 secured to, the valve body extend also laterally, one on each side of and parallel to the said valve stem 8. An

operating rod 11 pivotally connected tothe arm 9 at the outer extremity'thereof is also pivotally secured to the spindle 8 and passes through a slot in the arm 10; this arrangement being such that motion of the Paton-ted June 20, 1922."

Application filed December 10, 1919. Serial No. 343,785.

saidoperating rod 11 in a substantially horizontal plane will either open or close the valve 7. A spring 12, attached at one end to the said rod 11 and secured toa fixed frame at the other extremity tends to retain the rod in a position in which the valve 7 is closed.

Secured to the rod 11 intermediate the ends thereof is a connecting rod 13; the outer extremity of the connecting rod 13 bein pivotally secured to the extremity of a ro 14; pivotally mounted at a point intermediate its ends to a fixed frame or bracket indicated by the reference numeral 15. To the upper extremity of the rod 14: is pivotally attached a rod 16, whichis secured at its other end to a lever'arm 17 secured to the pivotally' mounted closure 18 in the ejector duct 1. The closure 18 may be of any type desired,

but in the present instance I have shown'it in the nature of a'valvelocated within the duct and adapted to be swun up into a cavity 18 in the roof ,of the p pe. seenthat any motion of the arm 11 in a di- It will be rection designed to open the valve 7 will,

through the medium of the connecting rods 13, 14 and16, and the lever arm 17, swing open the pivotally mounted closure 18 located atthe outer end of the duct. The spring 12 which normally holds the valve 7 closed, similarly operates to retain the 010 sure 18 also closed.

In the present instance, I have shown the arm 11 extending from the valve 7, bending slightly to the right, and a bar 19 pivotally mounted in the floor at one side of the said ejector is: so positioned that when the free end thereof is raised upwardly, the said rod will come in contact with the outer po-rtion of the arm' 11, the action between the said arm and thebar .19 bein such asto move the. arm 11 to open the va ve and the closure 18. Suitable means are provided to retain the bar 19 in the elevated position, in which position it will hold the arm 11 in position opening the said valve and closure.

The bar 19 is so located as normally to lie directly across the ash inl t opening 3 in the pipe 1, and in this position the said bar may belockcd down by a suitable locking device located in the floor adjacent the outer end thereof, thereby prohibiting removal of the cap 8 which is adapted to close the opening 3.

In my present invention, I propose to secure the said cap 3 to the bar 19 so that elevation of thesaid bar will uncover the hole 3. By means: of outrigger arms 20 extending from the bar 19 laterally over the air inlet opening 4 in the pipe 1, to which outrigger arms the cap 4. normally closing said opening is attached, I am enabled to open and close the air inlet opening simultaneously with the ash intake opening 3.

From this description, it will be seen that with the elevation of the rod 19, the various openings in the ejector duct 1 are thrown open, and at the same time a stream of the operating fluid, such as it may be, is injected into the duct oi the pipe 6 and the nozzle 5. So long as the rod 19 is retained in the elevated position, the ejector remains in operation, but with the lowering of the rod 19, the operating fluid is shut off through closing of the valve 7 and the same time the closure 18 and the plugs 3 and 4: are brought to their respective seats, thereby effectually sealing the duct 1 at all points and making the same substantially watertight at both extremities.

At the outer end of the duct 1, I have shown a nozzle 25 extending through the wall of the duct. The nozzle 25 is attached to a water pipe 26, and a conicalplug or similar valve 27 controls the flow of water therethrough. The purpose of this nozzle is to discharge a jet of water through the end of the duct, as indicated in Fig. 3, thereby to a. great extent eliminating the dust from the ashes which would otherwise settle upon the sides and surfaces of the boat.

I have shown means interconnecting the rod 16 and valve 27 whereby the said valve may be operated in conjunction with the opening of the closure 18, and therefore also in conjunction with the valve 7 andthe closures 3 and 1. The said interconnecting means consists of a bracket 28 attached to the rod 16, between which and the rod is loosely held the outer end of a lever 29 which controls the opening and closing of the valve 27. Thus the movement of the rod 16 in opening the closure 18 causes also the'opening of the valve 27 with a resulting discharge of water through the nozzle 25.

In Figs. 6 and 7, I have illustrated a modified form of my invention, in which the arrangement 18 such that the bar 19 extends 19 when the same is elevated. In this in-' stance, I have shown the rods which govern the opening of the closure 18 connected directly to the bar 19 by means of a link 22. The point where the said link joins the bar 19 is at a point above the pivot 19 of the bar, so that when the outer end or" the bar 19 is elevated, the rod 1% is swung on its pivotal mounting in such a manner that the closure 18 is opened. As the bar is elevated, it contacts with the outer end of the arm 11, and in the manner already explained opens the valve 7, 7

Suitable means are provided for retaining the bar 19 in the elevated position in which the conveyor is in operation. ilVhen the bar 19 is lowered, it first passes from contact with the arm 11, which is pulled back to its normal position in which the said valve is closed by means of the spring 12, and the bar 19 being completely lowered, there results the closing of the closure 18 and of the two intake inlet openings 3 and 4t", all in the manner previously explained. A spring retainer 23 is located adjacent the outer end of the rod 19 and retains the rod in the normal horizontal position.

The advantages of a structure of this sort are numerous. In the first place, a single motion of a single element puts the ejector into operation and opens the valves and the various plugs and closure caps which normally seal the ejector pipe, while the opposite movement of the said single element accomplishes a shutting down of the active elements of the ejector and at the same time the sealing of the ejector pipe; this intercom nected mechanism rendering the ejector sul stantially tool-proof and safe for use in vessels where conservation of power is a prime necessity.
